Which reminds me.... I still need to get The Planets.... I keep telling myself to get it...

Sorry if I never responded to you Boris, but yea, 100+ components might be a little out of my range, but I guess the best way to learn things is to try?!
Haha, sure. but after I updated the design it's kinda closer to 200.

Yep, got it.

Why's that?

Do you know which post bowei made with the P-H-like description of P-T? I forgot to bookmark it.
Here's my slightly edited version: Warning: Spoiler! (Click to show)
Project-T Fully Discrete Amplifier


Introduction:

Project-T is a fully discrete headphone amplifier with the design goal being to create a high end fully discrete amplifier at a fraction of the cost of what is currently on the market.

Our designer uses practical audio design and engineering to create a discrete amp that neither hogwash nor snake oil. The muting relays and fully discrete PSU enables Project-T to perform at its best weather you are driving IEMs or full-sized headphones.


What is Project T:

Project-T is a project by b1oLABS to test and produce a fully discrete unit. Armed with the technical knowledge, b1oLABS is here to produce an affordable unit for everyone. The T in Project T stands for Transistor as this is a fully discrete headphone amplifier.


Why P-T?


Affordability:

The goal is to use audio design with no exotic components nor nonsense measures to produce a great affordable discrete amplifier.


Fully Discrete:

By using a fully discrete design, this allows out engineer to fine tune every aspect of the amplifier. Most notably the output DC offset and input bias current for the amplifier section, these aspects out perform most commercial op-amps and ensures no pop/clicks even when driving the most sensitive IEMs.


Universality:

With a muting relay on power on and off, fluid gain levels, IEM’s and full size headphones will be well accommodated.


DIY-Ability:

Built from the ground up by hand. Project-T allows you to also fix or add changes to P-T. No micro solders preventing you from changing parts yourself. If we can build it from hand, you can change it by hand.


Community:

The diagrams and files on how to make a P-T will be made available to the public under a general use license. You can build one yourself under the condition that is is not for commercial purposes. The idea is to allow each and every single one of you, the ability to build your own affordable discrete amp. The enthusiast community is small, and only by our measures together, can we look forward to the future of this hobby. b1oLABS supports the enthusiast mindset of the world and wishes for DIY’ers to rise up.



The Features of P-H:


Dual-tracking Bipolar PSU design ensures balanced supply rails

Capacitance multiplier PSU design provides excellent load regulation and ripple rejection.

Muting circuitry ensures no pop/click at power on/off

2-stage design ensure constant input impedance

AC-coupled design prevents possible dangerous DC from entering the system

Sziklai pair used in input stage to minimize input bias current (less than 10nA, better than most op-amps)

Output offset adjustment ensures minimal output DC offset so that the unit can be used with even the most sensitive IEMs

DAMMIT!


Im an engineering student!!


... -_- :'( doing un engineering stuff frown.gif
You are?? eek.gif (no offense)
I thought you're really good at humanities too......

Sure, Ill give you the schematics.

There isnt a solidifed list right now anyway smily_headphones1.gif
What kinda course is that??

Here's the list:
(I only ordered 5 PCBs)
  1. me
  2. mech
  3. mech
  4. csirus
  5. panthers

Um... sorry, they kinda asked first.

If we get 5 more ppl, Ill order more, Alternatively, you can go get the PCB made yourself.

Speaking of P-T PCBs, It seems like they have so many colors available, I bet I can ask for a cyan PCB if I wanted to tongue.gif
So anyway yeah, we got black.

Cyan would be a unique colour. The one I bought from OSH Parks is a red-purple colour and it attracts a lot of fingerprints. XD

very nice. also new tripeace chapters. Guess they were scanning a lot and saving it up :)

How does one attracts fingerprints??

(rather what's it gotta do with color?)

I think the greasy fingerprints just show up more on purple. I don't get the same result with the black JDS Labs C5 though. Weird.

Why's that?

 

 

Because I leave my computer in Japanese mode so I can easily setup, compile, and upload game for my thread. Well, consequently when setups have multiple languages available, they show in Japanese. So I need to switch back to English locale for a bit to install it, which requires a restart of my computer. Thus I don't feel like doing that now.

Where does the electronic bit come from?

we have to deal with it a lot

lol what's wrong with the installer showing in jap?

 

which reminds me.... I've been using Multisim in japanese for quite a while now biggrin.gif

pahhhhhhhhhhhhhhhhhhhhhhhhhhhh. Looks like sony's PET diaphragm was/is the longest lasting. Still have yet to see how long the LCP can hold out.
